What This Test Measures

This test detects the presence of antibodies (specifically IgG and IgM types) against SARS-CoV-2, the virus responsible for COVID-19. IgM antibodies typically appear shortly after infection and decline over time, while IgG antibodies develop later and persist longer, indicating a stronger immune response. The test is qualitative, meaning it only tells you if antibodies are present rather than their exact amount.

Why It Matters for You

While this test can suggest past exposure to COVID-19, it does not confirm current infection. Antibody presence does not guarantee immunity or protect against future infections. This test is often used as part of a broader evaluation, such as in vaccination studies or for monitoring immune response.

How the Test Works

Blood is drawn from a vein in your arm. The sample is then tested using an immunoassay method to detect specific antibodies. The result is reported as positive, negative, or indeterminate if the test cannot definitively identify antibodies.

Sample Collection and Preparation

A healthcare provider will collect your blood sample in a sterile tube. This sample is sent to a lab where it is processed and tested for the presence of antibodies without further manipulation by you.

Frequently asked questions

Why might I get this test?
This test may be used in situations like post-vaccination monitoring, evaluating past infection history, or as part of research studies. It is not a diagnostic tool for active COVID-19 infection and should not replace other tests like PCR or antigen tests.
Can antibodies protect me from future COVID-19?
Antibodies provide some protection, but immunity is not guaranteed. Vaccination and booster shots are recommended to enhance protection against severe illness or reinfection.
What does a positive result mean?
A positive result suggests your body has likely encountered the COVID-19 virus before, but it does not confirm when or how you were infected. This result should be interpreted by your healthcare provider in the context of your medical history and other test results.
